If you are going to merchant something, first you should try to find a perm buyer for a pretty high price, on an item that has at least a 15gp price range (like coal). Now, with coal, you would go to fally (because thats where all the coal goes through) and then you say "Buying all coal ___gp". Most people will try merchanting buy buying coal for 170ea, so you buy for 175ea, or 180ea. People will sell you random amounts, 18, 488, and 2392 coals, buy them all! Once you get lots, you go to your perm. buyer and sell to him for (in this example) 200ea, or even maybe 210ea. If you don't have a perm. buyer, then using the same technique, instead of trying to sell for 200ea like everybody else, sell for 195ea, and you will sell more and therefore make more money. -obi P.S. I should write a guide lol
